Do you think there will be a noticable performance difference in our car with the different fuel?

The Renegade HR 102 unleaded has made a difference in some low compression applications, so it's possible you might see an increase. But a very different tune up will be required to get the most out of the fuel.
A number of Stock Eliminator championships have been won using 118 octane race gas in low or relatively low compression engines. It has to do with the burn characteristics of the high octane fuel rather than the octane itself.
